- "To all whom t may concern:

associate journal boX. i

.ends ofI the truck.

Be it "known that I, HERMAN C. Pinnen, a citizen of the UnitedStatesfre'sidingat Blue Island, in the county of Cooltand the State ofIllinois, have `invented a cer tain nevv'and useful Improvement inRailroad-Gar rllrucks, of Whichv the following is afull, clear, concise,and exact description. j My invention'relates to car trucks and residesin the employment of U bolts for assembling the journal boxes With thecai' truck side frames.` Thesides of each` U bolt that performs` such" afunction aref` placed in 4the `plane of the contiguous `side frame so`that the U fbolt inconjunction With the side `franielwith WhichA it isasseinbled may deinespace for receiving the lVhere the side frames areformed With `as`seinbledupperand lovverarch bars the U bolts also`prei'erablytake part `ininaintaining these `arch bars in assembly attheThe bases of the U bolts desirably underlie `the journal boxes v and arepreferably formed with eyeswhich receive tie rods that assemble thebases of y the U bolts with the mid and underlying j portions of theside frames.

The invention Will be more fully eX- plainedin `connection with theaccompanying drawing in" which Fig. 1 is a side view of a car truckvconstructed in accordance Witlitlie preferred vembodiment of theinvent-ion; and Q isa view frombeneath illustratingfa portion of the cartruck.

Like parts are indicated by similar char'- aeters of referencethroughout' bothfigures. Thetruck side frame illustrated vincludes anupper `arch bar"1, a lower arch` bar `and thebolster guide bars 3 and 4.Each j side of the truck has'l` such al side` frame.

A s the `drawing only' illustrates tlie'comf plete construction'at oneside of the truck,

lthe construction. of buifone side Will be alone described, it beingunderstood that such de` scription pertainstothe construction at eachsprings are seated upon the seat 7 carried upon the lower archfbar. Theupright U bolt 8 which serves to define `the positions yof `the springs5 and 7 has its base below the seat" 7 and its sides passing through theupper arch bar with which "tliebolt is through the outer s rino'sl and 7andthe truck bolster branches 10,"103`. `Ilie middle 1 truck bolsterbranch 102 is disposed between the guide bars 3 and 4 While thetruckbolster branches 10', 103 are upon the outer4 sides of these guide bars,'this structure formingthe subject matter of another application, SerialNo. 602,369,1iled Feb. 12, 1924.1

' `In the structure shown, `the arch" bars are brought together at the`ends of the frame above-the journal boxes 11 that en-` close, each, thebearing block; 12 resting? upon the corresponding car axle 13. The

upper portion of each journal box'is formed with a top flange 14; havingupright apertures, spaced apart longitudinally ofthe truck, throughwhich the uprightV sides of theiU bolt 15 are passed. The base of this Ubolt underliesV the journal box, this U bolt base and the sides` of theU bolt Vclosely einbracing the portion ofthe associate journal boVX thatextends downwardly from the car axle. The nutsiG upon the upper ends ofthe U bolts are screwed firmly; down upon the upper arch bar and serveto clamp the 4adjacent ends of` the arch bar in assembly With each otherand in assembly With the corresponding journal box. j

Each'U 'bolt 15 is formed With an eye 17 `on its base, this` eye 'beingpreferably formed by siiitablycuiling the rod from which the U bolt 15is made.

Linkage assembles the bolts 15 with the side frame, suchlinkagej'nfeferaliily inincluding two cliaiulilie links 18 .vhose outerends arefreceived inthe eyes L7 and whose inncrQei'ids 4are tirlnly heldbetiieeii the spring seat 7 and the lower arch bar. 2 at the' niid andbottoni portion of the side l frame.

`It is obvious that changes may be nia-de without departing from .thespirit of niy invention. j ,j
